During his time with the company, he was involved in launching its foray into the internet, digital cable and its purchase of 11 radio stations and seven TV channels from Rogers.

He also oversaw the acquisition of assets from Western International Communications, the relocation of the company headquarters from Edmonton, and its acquisition of Canwest Global Communications in 2010.

He stepped down after reportedly displaying belligerent behaviour toward investors.

The company’s then-president, Peter Bissonnette, told CBC News at the time that Shaw was always known to be “a little feisty.”

He was also known for supporting Canadian charities and educational organisations, donating $19 million to Shawnigan Lake School in 2014.

Outside of Shaw, he also participated in a number of organizations in the cable industry, serving as chair of the Canadian Cable Television Association from 1996 to 2002, and sitting on the boards of CableLabs, Microcell, Cancom and @Home.

His brother said his contributions helped make the company what it is today.

“As an operator, a deal maker and a strategist, Jim continued building the foundation started by our father, JR, to create a Canadian business leader and household brand across Western Canada,” he said.

Employees of Shaw and its affiliates, former business contacts and friends shared their condolences with the family on social media.

Jim Shaw was a pioneer in business who changed the telecommunications landscape. He was a philanthropist who made an enormous difference in his community.

Edward Rogers, chair of Canadian telecom Rogers Communications, shared his sympathies with the Shaw family in a release.

“We have known Jim for many years and we are truly saddened to hear about his passing. We would like to extend our sincere condolences to Jim’s family, friends and to everyone at Shaw. Jim was a brilliant man and a fierce competitor. He was a confident entrepreneur who had a transformative and lasting impact on the Canadian cable landscape. He will surely be missed,” Rogers wrote.
